This morning Soleil has downgraded Sunpower (SPWRA) to Neutral from Buy based on valuation due to a big run over the past few weeks.  However, the stock continues to look much more bullish and surged with heavy volume off the 50 day moving average yesterday.  The stock has been helped recently by takeover rumors.
